CAR -COUPLING.

Application filed September 19, 1914. Serial No. 862, l81.

To all whom it may concern Be it known that .l, Grouse J. Wrrmnrr, a zen of United States, and resldent of lwaukee, the county oi Milwaukee and State of Wisconsin, have invented certain and useful Improvements in Car-Gouplings, oi which the following is a specification.

My invention relates to car couplers of the type lmown as the arrow head and has particular reference to a novel, automatic cenmecha' ism for use in connection therewith. 1

in many manufacturing establishments,

mines, yards, etc, a series of cars will be employed which. are not adapted for interchange trafiic with standard railways and are intended for use solely in connection with the particular establishment owning the cars. Such cars may he of light construction and operated on other than standard gage tracks. However, coupling means must he provided for the cars and as the loads are not great nor the requirements severe, a coupler of the arrow head type may be used to advantage in preference to one of the M. G. type. It is to a coupler of the a row head type that this invention particu- 1 'y, relates the improvement residing in the means employed for automatically centsring the coupling member without the use of springs ,or other elements which might v become weakened or broken.

The invention will he more readily understood by reference to the accompanying drawin s, wherein,

Figure l is a side elevation of a car coupler constructed in accordance with my in-- vention, and, 2 is a plan view of the same.

video the pivot for the coupling member or' knuckle l lhe shank 16 of this member terminates in an arrow head it, which may In the drawings the head of the couplerbe of any desired shape in order to properly engage with the mating head. This pivot pin preferably engages the shank 16, through a squared aperture in order that the pin may move with the coupling member. Above the head 10, and also pinned to the pivot 15, is a hand lever 18, by means of which the coupling member may be manually shifted. The rear portion of the shank 16 extends into a recess 19, formed in the head 10, the shank being bifurcated as at 20, a link 21, extending between the bifurcations and being pivotally held by means of a pin 22. The opposite end of the link 21 is apertured and accommodates a stud 23, forming a portion of a bell crank 24:, pivoted at 25, to a bracket member 26, secured to the Wall 14. The bell crank is provided with a weight 27, on its free arm.-

The operation is as follows: The parts being assembled as shown, the bell crank exerts tension on the link 21, and tends to straighmn out any deflection oi? the coupling member until the axes of the pins 15, 22, 23, are in alinement. lVhen the arrow head is shifted to one side as will occur when the coupling operation is effected, the weight will be lifted but there is a constant tendency toward the bringing of the arrow head into longitudinal alinement with the bell crank.

The parts are very simple and will not readily become out of order and as no springs are employed the objection to breakage along that line is overcome.

The parts may be modified to a certain extent all without departure from the spirit of my invention.

ll claim:

ii. In a coupler, the combination of a recessed head, an arrow head coupling member pivoted in said head at a point intermediate of the length of the coupling member, a link pivoted to the rear end of said memher, and a weighted bell crank acting upon said link and tending to maintain said link and coupling member in alinement, substantially as described.

.2. In a coupling device, the combination of a poclret, a coupler pivoted therein, a link pivoted to the rear of the coupler and. in line therewith, and a weighted bell-crank pivot pler and normally in alinement therewith,

ed at the rear-of the pocket and diretly com nected to said link, substantially asdescribed. v

3. In a coupling device, thefco'nibination of a pocket, a coupler having a; fixed pivbt in said pocket, a link connected to said coutransvrse horizontal ivotzatthe rm 0;?- the pocket and directy connected to said 10 link, substantially as des gribed,
